ATI AVIVO High Definition Content Accelerator

High Definition video content is right around the corner and 2006 is reminiscent of the time when DVD's were first released. HD videos are promising to be very taxing on system recourses too. In order to meet the High Definition processing task, ATi has built into every X1000 series core what it calls 'AVIVO technology.' With the computer industry heavily pushing the digital home, it makes sense for ATi and nVIDIA to integrate some form of High Definition accelerators into each companies respective products. We just wish the silly names wouldn't always have to follow suit.

ATI Avivo for High Definition Content

Despite an interesting name, AVIVO does not stand for anything specific. It is a collection of different video technologies that share a common name, like Centrino or ViiV for example. First and foremost, ATI's AVIVO includes a hardware accelerator for MPEG-2/DVD Microsoft Windows Media HD video standards (WMV HD) and H.264 standards. As mentioned earlier, VIVO is built into all X1000 series videocards so even entry level PC's can be used as Home Theatre PCs (HTPC) or Personal Video Recorders (PVR) with the appropriate 3rd-part software applications. AVIVO can automatically adjust gamma and colour correction, and that should enhance picture quality too.

High Fidelity Colour allows for 10-bits per colour channel, which translated basically means a more vibrant picture. There is also a high quality 12-bit analog-to-digital converter to reduce picture noise.

To test AVIVO's HD accelerating capabilities, we played a HD video through Windows Media Player 10 (the movie can be downloaded from Microsoft's WMV HD Content Showcase). The Discoverers (IMAX) video is available in both 720P and 1080P formats, and CPU utilization was monitored during playback through Task Manager to give a general indication of system load.

ATi's AVIVO performs very well and CPU usage when running the 720P version of the Discoverers video never broke the 30% load mark!

The 1080P version obviously has more detail, which is why CPU usage is slightly higher but still pretty reasonable. On the whole, AVIVO appears to be generally more efficient than nVIDIA's PureVideo.

Overclocking, err lack there of...

This is where the overclocking section usually goes in a PCSTATS videocard review, however the MSI RX1800XT-VT2D512E simply did not want to play that game. While the MSI RX1800XT-VT2D512E would officially overclock, the R520 core would automatically clock itself back to stock speeds within five seconds of running a 3D benchmark. This anomaly was present no matter what overclocking program was applied. So, no overclocking results for you unfortunately.

experts tip: override the fan speed control
most videocard heatsink fans are temperature controlled, as this allows for decreased noise levels without hurting the longevity of ics that require active cooling. however, if you're into overclocking and feel the need to override the hard coded fan speed settings, you can do just that with a third party program like RivaTuner. Doing so is quite easy; first load up Rivatuner and then look under the Target adapter section. Go to Low-Level system settings and click the Fan tab. Enable the low-level fan control box. Once that's done, change the radio box option from auto to fixed and adjust the slider to whatever speed setting you prefer. Running the videocard fan at a steady 100% is great for temperatures (and for users overclocking to high core speeds), but it is pretty hard on the ears so keep that in mind.
